Alexandr Buryak

摘要:

利用K. Saito,$A_{r-1}$ -奇点的极小变形的参数空间具有Frobenius流形结构。朗道-金斯堡镜像对称说,在平面坐标中,这个弗罗贝纽斯流形的势等于$r$ -自旋曲线模空间上某些积分的生成级数。在本文中,我们表明,作为平面坐标的函数的微小形变的参数,也有一个简单的几何解释,使用扩展的$r$自旋理论,首先考虑T。J. Jarvis,T. Kimura和A. Vaintrob的研究,并在E.克拉德河J. Tessler和作者。我们对奇点$D_4$证明了类似的结果,并给出了奇点$E_6$和$E_8$的表达式.

英文摘要:

By a famous result of K. Saito, the parameter space of the miniversal deformation of the $A_{r-1}$-singularity carries a Frobenius manifold structure. The Landau-Ginzburg mirror symmetry says that, in the flat coordinates, the potential of this Frobenius manifold is equal to the generating series of certain integrals over the moduli space of $r$-spin curves. In this paper we show that the parameters of the miniversal deformation, considered as functions of the flat coordinates, also have a simple geometric interpretation using the extended $r$-spin theory, first considered by T. J. Jarvis, T. Kimura and A. Vaintrob, and studied in a recent paper of E. Clader, R. J. Tessler and the author. We prove a similar result for the singularity $D_4$ and present conjectures for the singularities $E_6$ and $E_8$.
